Galaxies NGC 4527 & NGC 4536
NGC 4527
The galaxy NGC 4527 was discovered by William Herschel on 23 February 1784. He listed it as faint nebula II 37 and noted: «Pretty bright, extended, north preceding, south following, much brighter in the middle.» [463] The orientation should read «south preceding, north following.» John Herschel recorded it as h 1330 = GC 3076 with the description: «Pretty bright, large, pretty much extended 60°; much brighter in the middle.» [467]
